v 4 c. (01. 214-.ss) The invention relates to a mobile conveyer In the accompanying drawings:

mechanism and more especially to a conveyer for Figure 1 is a side elevation of a truck showing unloading and delivering loose material from the conveyer constructed in accordance with the vehicles. invention applied thereto.

The primary object of the invention 7 is the Figure 2 is a top plan view, the truck including 5 provision of a conveyer of this character, wherein its hood being partly broken away. v the same is attached to and driven by a motor Figure 3 is a vertical transverse sectional view truck for unloading coal, stone and similar loose on the line 33 of Figure 1. materials without lifting the whole load and Figure 4 is a fragmentary vertical longitudinal l0 truck body, the conveyor being capable of operasectional view through the truck and the contion through an arc of one hundred and eighty veyer. 1 degrees onaverticalaxis and israised and lowered Similar reference characters indicate correto the required height when making delivery spending parts throughout the several views in therefrom. the drawings.

The yoke H the said conveyer to be swung to any position supports an unloading and delivering conveyer and height and yet dispose the receiving end hereinafter fully described. directly below the discharge end of a feed belt The unloading and. delivering conveyer comcarrying the coal or other material as emptied prises an elongated frame I8 which at opposite, from the truck. ends is provided with stationary and adjustable A still further object of the invention isthe bearings l9 and 20, respectively, the adjustable 46 provision of a conveyer of this character, which bearings being interfitted with the yoke l6 so that is comparatively simple in its construction, thorthe frame l8 can be swung vertically to have the oughly reliable and efficient in its operation, outer end of the conveyer extend to a desired readily and easily adjusted, and inexpensive to height. Thesebearings have passed therethrough manufacture and install. axlesil carrying rollers 22 over which is trained 50 With these and other objects in view, the inthe endless conveyer belt or apron 23, the rollers. vention consists in the features of construction, being fixed to the axles 2i and such belt or apron combination and arrangement of parts as will 23 is coextensive with the length of the frame be hereinafter more fully described, illustrated I8 and slightly protrudes beyond opposite ends in the accompanying drawings, which disclose thereof. The axles 2| at the outer side of the conthe preferred embodiment of the invention, and veyer have fixed thereto sprocket gears 24 over pointed out in the claims hereunto appended. which-is trainedan endless sprocket chain 25,

to a. driven shaft 34 which through gear and shaft connections 35 and 36, respectively, with the truck motor enables the'motor driving of the conveyer. The connections 35 and 36 are in association with the transmission control 31 of the truck.

The bracket |5is of a kind to locate the yoke i6 with the conveyer frame |B swingingly fitted therewith beneath the body ID at one side of the chassis ii of the truck. Mounted on the body ID at that side where the conveyer is located is a bracket 38 in which is journaled a windlass 39 on which is to be wound and unwound a hoisting cable 40 operatively connected at 4| with the conveyer frame |8 so that the latter may be raised or lowered and the raising thereof had at any desired height. The Windlass 39 has fixed thereto a worm gear 42 with which meshes a worm screw 43 operated from a hand crank 44 so thatthe -conveyer frame IE will be manually controlled for raising and lowering of the same. The cable 40 is trained over guide pulleys 45 and 46, respectively, and one end of this cable is fixed at 41 to the bracket 38 while the-other end is adapted for winding on and unwinding from the Windlass 39. The pulley 45 and the attaching end 41 of the cable 40 are free for rotation so as not to interfere with the horizontal swinging of the said conveyer through an arc of one hundred and eighty degrees on the vertical axis constituted by the stud 32 of the yoke i6 and in this manner unloading and delivering material from the truck may be had fore and aft and throughout one side of the latter. The Windlass has cooperating therewith a suitable latching device 48 for holding the Windlass stationary when the cable 40 is wound thereon and thus sustaining the conveyer in its elevated adjusted position yet such conveyer can be lowered at will on releasing the device 48.

The frame iii of the conveyer is preferably made in two sections connected by a hinge 49 to permit the folding of the frame by the swinging of the outermost section downwardly and inwardly against the inner section thereof. These sections when unfolded carry abutments 50 at the hinge point thereof so as to maintain alignment in the unfolded condition'of said conveyor and rigidly in this condition, there being no possibility of accidental folding of said conveyer when operating for unloading and delivering material from the truck.

The body ID of the truck A has formed in its bottom 5| discharge openings 52, these common to the compartments l3 created by the partitions I 2 within said body and each opening 52 is closed by a slide gate 53, hand operated, while confronting the said openings 52 is a feed belt 54 within a frame, 55 fixed to the under side of the bottom 5| of said body and disposed in a longitudinal direction thereof. This frame similarly to the frame I8 is equipped with stationary and adjustable bearings 56 and 51, respectively, and the end rollers 58 over which the endless belt 54 is trained, the adjustability of the bearings20 and 51 being for the purpose of tightening of the belts 23 and 54, respectively. The axle 59 of the roller 53 at the end of the belt 54 next to the conveyor through driven gear and shaft connections 50 and iii, respectively, with the gear and shaft 33 and 34, respectively, will drive the belt 54. The conveyer frame l8 at the end next to the belt 54 has built thereon a receivin hopper 62 for accommodating material discharged from the said belt 54 for the acquiring of such material by the con-' veyer belt 23 which will unload and deliver its material from the outer end of the said conveyer at a selected point of deposit. The material within the body I0 is admitted onto the belt 54 when the gates 53 have been manually opened as the material will fiow through the openings 52 in the bottom 5| of said body directly onto the said belt 54 whence such material will be carried thereby onto the conveyer for the unloading and delivering of such material thereby.

The frame I! is equipped at its opposite sides with side guards or boards 63 to avoid the material falling from the conveyer atpopposite sides thereof, this being common to endless conveyer constructions. I

It will be clearly evident from the foregoing description taken in connection with the showing in the drawings that the contents of the body IU of the truck A can be readily and conveniently unloaded and delivered throughout one side of the said truck at a selected point thereof or fore and aft of this truck and additionally the materialduring unloading and, delivery can be raised to the required height without lifting the whole load and truckbody. h
